OBVILLE DOUGBERTY, OF THREE RIVERS, MICHIGAN.

CONCRETE POST OR POLE.

Specification of Letters Patent.

Patented Jan. 11, 1910.'

Application led August 28, 1908. Serial No. 450,780.

To all 'whom fit may concern:

Be it known that I, ORVILLE DOUGHERTY,

a citizen of the United States, residing at` strong in proportion to its size and the amount of material used therein.

Another object is to provide an improved post, or the like, which is very economical to manufacture, and one in which the reinforce may be very easily placed, requiring no support other than the mold walls during the manufacture of the post.

Further objects, and objects relatingto structural details, will definitely appeal from the detailed description .to follow.

I accomplish the objects o f my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out inthe claim. I

' A structure embodying the features of my invention isclearly illustrated in the accom' panying drawing, forming a part of this specification, in which,-

Figure l is a plan view of a post'embodying the features of my inventlon, it being shown in a mold in which it is manufactured. Fig. 2 is an enlarged cross section, taken on a line corresponding to line 2--2 of Fi l. Fig. 3 is an enlarged detail longitu inal section, takenon a line corres onding to line 3-3 of Fig. 1. Fig. 4 is a etail plan view of a piece of the reinforce. Fig.

-5 is an enlarged crosssection, showing a modified form of reinforce.

In the drawing, the sectional views are taken looking in the direction of the littlearrows at the ends of the section lines, and similar numerals of reference refer to similar parts throughout the Vseyeral views.

Referring to the drawing, the body 1 of my impro-ved pole or post is preferably U- shaped in cross section, and is formed of a suitable concrete mixture of cement. sand and fine gravel. This I preferably form in a mold 2, which is formed of sheet metal and is U-shaped in cross section, as clearly appears from the drawing. The reinforce 3 is formed of reticulated sheet` metal,'the strands being fiat and`arranged at an angle to the surface of the body 1. as illustrated. The reinforce is also preferably U-shaped in cross section and has its edges 4 turned inwardly upon itself to add strength thereto at this point. The reinforce isnearly the same dimension in cross section as the body. so that it lies close to the surface thereof. The reinforce is provided with projecting portions 5 at intervals, which lie substantially flush with the surface of the body, thereby spacing the reinforce relative to the surface of the body, and supporting it during the process of manufacture, the (proj ecting portions resting against the mol walls, as is illustrated in the drawing. This enables the arrangement of the reinforce in the mold and the wet concrete can be shoveled into the mold upon the reinforce, the concrete passing therethrough.-that is, such l portions of the concrete as are desirable for the surface of the body -will pass through the reinforce. If there should be any coarse gravel or stone in the concrete, it is pre.

vthe reinforce, instead of being portions punched out therein, as is illustrated in Fpreferably provide the reinforce with a border 6 at each edge which further strengthens and reinforces the bodyl.

While my invention is particularly designed by me for use in fence posts, it is a plicable to poles and the like, being especial y desirable for use where light, strong posts orpoles are desired, as it possesses great strength in proportion to the amount of material used therein, and is capable of withstanding shocks. such as it is likely to receive, when used as a fence post, by animals runninng o r pushing against the fence.

I have illustrated my inventions in detail in the form preferred by me. I am aware, however,'that they can be varied considerlos ably in structural details Without departing therefrom, and I desire to be understood as claiming the same specifically, as well as broadly, as I have indicated in the appended claim.

Having thus described my invention, what I claim as new and desire to secure -by Letters Patent is:

The combination with a concrete body, of a reinforce embedded therein, said reinforce being formed of reticulated metal having outwardly-projecting spacing members at intervals, the outer end of said spacing members being substantially flush with the surface of said body, said spacing members 15 being in the form ofv off-set loops continuous with said body.

In Witness whereof, I have hereunto set, my hand and seal in the presence of two witnesses.

ORVILLEl DOUGI-IERTY. [14. s]
